Overview
Among the calmer damselfish, hardy enough for a first marine tank and content in a small shoal. It eats flake, pellet, and frozen foods plus some algae-based food, and it is completely safe with corals and invertebrates. Mild squabbles happen inside a group, so provide enough rock for every fish to claim a spot.
In the wild
Lives in lagoons, on sheltered reef flats, and around isolated coral heads across the Indo-Pacific, often with a small group holding station over one coral outcrop. It stays near cover but feeds up in the water. Recreate that with scattered rockwork, gentle flow, and open water above.
Good to know
Pomacentrus pavo is a damselfish in the family Pomacentridae, described by Bloch in 1787, and it grows to about 8.5 cm. The blue-green body is marked with fine dark scale edges and a yellow forked tail. It spawns like a typical damsel, with demersal eggs guarded by the male, and it is produced by commercial captive breeders.
Did you know
Its species name is Latin for peacock, and the color earns it: the body flashes from deep sapphire to teal green as the fish turns through the light.
